Introduction: Several new bifunctional reactive dyes of the Sumifix Supra range that carry monochlorotriazine and sulphato ethyl sulphone reactive systems were developed and their dyeing performance studied. Suitable characteristic properties and fastness properties were examined over the knitted cotton fabrics. The dyes were characterized by spectral data and elemental analysis. The dyes struc...
In order to realize the anhydrous dyeing of linen fabric with reactive dyes in supercritical CO2, a CO2 ionic liquid reverse micelle system was constructed, and process this studied. system, can be dyed without special pretreatment. The results show that depth significantly improved by increasing amount surfactant. With increase temperature, first increases then decreases. pressure displays lit...
The fiber, dye and dyebath variables which affect the batch dyeing of polyester with disperse dyes are discussed, as are some of the chemical properties of disperse dyes which influence the normal conditions of dye application, stripping and reduction clearing. Discussion of the continuous dyeing of polyester is deferred to a iater chapter on dyeing polyester/cellulosic
The effect of cationic modification of cotton fabrics, using cationic agent (Chromatech 9414) on direct dyeing characteristics was studied in this work. Cationization of cotton fabric at different conditions (pH, cationic agent concentration, temperature and time) was investigated and the optimum conditions were determined . Nitrogen content of cotton samples pretreated with cationic agent was ...
This study optimized the salt free reactive dyeing process using Taguchi approach. Dyeing of cotton fabric with dyes is popular because its bright and brilliant color in various shade ranges. Cationization ALBAFIX-WFF on was carried out exhaust method. To determine optimum conditions, two types multiple characteristic parameters, including single value conversion method maximization method, wer...
In this study, the influence of dyeing on the antibacterial efficiency of polyamide and polyester fabrics loaded with colloidal Ag nanoparticles and the influence of the presence of Ag nanoparticles on the color change of dyed fabrics were investigated. Dyes C.I. acid green 25 and C.I. disperse blue 3 were used for dyeing of polyamide fabrics, while dye C.I. disperse violet 8 was used for dyein...
